Hi Sergei,

Apologies for the delay. I am extremely sorry, I was struck on something important
It's great that you figured out the solution.

Whenever you set a dirty flag as mentioned in the previous thread, the quota values will be recalcualted.
Yep, as you mentioned there are lot of changes that has gone in from 3.7. We have
introduced Inode-quota feature in 3.7, then we have implemented the Quota versioning
in 3.7.5 and then enhance quota enable/disable feature in 3.7.12. So a lot of code changes
has been done.

In case would you like to know more, you can refer our specs[1].

The problem must have started because of an upgrade to 3.7.12 from an older version. Not sure exactly how.

It seems that it did the trick. The usage is being recalculated. I’m glad to be posting a solution to the original problem on this thread. It’s so frequent that threads contain only incomplete or partially complete solutions.

Thanks,

I found an informative thread on a similar problem:


According to the thread, it seems that the solution is to disable the quota, which will clear the relevant xattrs and then re-enable the quota which should force a recalc. I will try this tomorrow.

Hi Selvaganesh,

Thanks so much for your help. I didn’t have that option on probably because I originally had a lower version of cluster and then upgraded. I turned the option on just now.

The usage is still off. Should I wait a certain time?

Thanks,
  Sergei

Hi Sergei,

When quota is enabled, quota-deem-statfs should be set to ON(By default with the recent versions). But apparently 
from your 'gluster v info' output, it is like quota-deem-statfs is not on. 

Could you please check and confirm the same on /var/lib/glusterd/vols/<VOLNAME>/info. If you do not find an option 
'features.quota-deem-statfs=on', then this feature is turned off. Did you turn off this one? You could turn it on by doing this
'gluster volume set <VOLNAME> quota-deem-statfs on'.

To know more about this feature, please refer here[1]

Hi,

Sorry, I missed the mail. May I know which version of gluster you are using and please paste the output of
gluster v info?

Hi,

I'm playing with quotas and the quota list command on one of the directories claims it uses 3T, whereas the du command says only 512G is used.

Anything I can do to force a re-calc, re-crawl, etc?

Thanks,
 Sergei
